lVlANUFACTURE OSF-BOOTS OR SHOESZ SPECIFICATION forming part of Letters Patent No. 262,552, dated August 15,

Application tiled February is, lSi.

.To all whom 'it may cmzceijnv Be it known that I, Hierin R. ADAMS, of Boston, county ot Suii'olk, State ot' Massachusetts, have invented' an Improvement in Boots or Shoes, ot' which the following description, in connection with the accompanying drawings, is a specification.

My invention consists in a boot or shoe having'its upper and its outer and inner soles united by means of metallic staples, such as hereinafter described, extended through holes made in the inner sole, and thence out through the upper and outer sole, the projections on the legs of the staples being so shaped as to permit the leather to be forced easily upon them, and thereafter to practically prevent the leather from being pulled from the staples.

My invention also consists in that improve.

ment inthe art or method of manufacturing boots and shoes which consists in providing the outer and inner soles and the upper of the boot or shoe with a series ot' holes to receive the sole-fastenings, placing the solefastenings in the inner sole with their pointed ends extended beyond what is to be the under side ot' the inner sole, placing the upper provided with holes over the ends of the said fastenings, applying the perforated outer sole or soles to the said i'asteniugs, and forcing the outer sole and upper down upon the said fastenings, as viill bc hereinafter described.

My invention-has for its object the production of a most serviceable and strong boot and shoe in a novel, Simple, expeditious, and cheap manner, without the necessity of slrille'd labor or extensive machinery. l

Figure l represents partof a hoot made in accordance with my invention, a portion of' the same being broken out to show the fastenings; Fig. 2, theupper provided with a series of holes near its edge; Fig. 3, the inner sole, with staples or fastenings set in it, the sole being placed on a suitable support; Fig. Jr, one ot' the staples or fastenings enlarged, and having its legs provided with projections in accordance with my invention; Figs. 5, 6, and

7, the outer sole, the inner sole, and heel, provided with holes for the reception of the staples or fastenings; Fig.' 8, a longitudinal section of the bootits soles and heel all being 188,2. (No model.)

placed ou a jack to be pressed or molded into close contact on the staples and to shape or mold the soles; and Fig. 9, a modilication to be referred to.

In the practice of my invention I prefer to take the upper a for the boot or shoe, and crimp it, as in United States Patent No. 243,422, granted to lne J une 28, 1831, to which reference may be had, wherein it willbe. seen that the upper, as it is crimped, is marked or creased to designate where it should be pierced or punctured to receive the sole-fastenings, and thus insure uniformity in shape and size of all boots made on any one form. Having crimped and marked theupper a,as described in the said patent, I next punch through it a series ot holes, the latter being-made preferably for best work in the irregular .or waved crease'or marked line made iu'crimpin g. i

'The outer sole, b, inner sole, c, and heel (l will be properly shaped in dies. lhe outer sole and inner sole for each boot or shoe are superimpressed one on the other, and, ifdesircd, the heel may also be placed in its proper posi-x tion in the same pile, and the solesand heel will then be-punched willi holes 2 for the reception ot the legs of the staples c or sole,- fastenings, to be hereinafter described, one of such staples'being shown in detail, Fig.'4, on a. large scale, to clearly illustrate the peculiar form of the projections ofthe legs. The holes arel madein the soles or soles and heel at one operation by means ota gang of awls suitably` actuated, as I shall describe in another applif` cation for United States patent to be made by me. The sole-fastenings, preferably staples'c,

such as shown, are then inserted through the holes 2in the inner sole, c, from what is to be its upper -or tread face. The staples c', inserted iu a like manner through the heel end ot' the inner sole, (sceFig. 3,) are, longer than those inserted through the shank and foro part of the inner sole, to tlius enable the heel to be united to the shoe by staples. The inner sole, having been set with staples, will be placed upon a rigid but thin snpporting-plate, j', (see Fig. 3,) at the topotthe post]"-- is thin, and vcryinuch,smaller in cross-section than would be a last to fill the upper, as when.

lasting in the usual manner, so that when the IOO upper a, provided with holes a2, is placed outside of or about 'the support f and inner sole, the perforated parts ft2-ot the upper may be readily placedover the legs of the staples.

The heel-stitfener, if used, will also be provid-V ed with a series ot' holes for the staples. The

upper having been applied to the staples'e' e', while the inner sole is sustained by thesupporting-plate f, the outer sole, plied tothe legs of the the heel d, proyided .with holes, will be placed on the longer staples, c', afterwhichtheouter sole and heel will be crowded well down upon the legs of the staples. The boot or shoe thus 'partially united will be placed on a stiff iron last, h, having-its shank Wproperly supported, and by blows upon theouter sole and heel, or by strong pressure against the outer sole and -heel by a suitable roll, forni, or die, the outer sole and heel will-be forced completely down on the staples, uniting the inner sole, upper, and outer sole by ineansof t'astenngs extending from the'tread-face of the inner sole outward through the upper and through or into the outer sole. While quently the sole will be molded.-

rlhe legs of the staples are so grooved or cut as topresent a series of cones the apices of which are turned toward the points of the legs of the staples, as shown fully in Fig. 4. This construction of the staple enables the leather to he easily7 forced upon the staples, and the projecting annular portions the cones 4 act as shoulders to prevent the re turn or movement ofthe outer sole from the ends ot' the legs of the staples. Staples ot' the shoe together kind described hold the material of the boote more positively and secure y than were the staples made with plain legs or simply corrugated. XVear4 and blows against the sole and heel-in walking act to crowd the.

sole and heel farther on the staples, and the staples, shaped as shown in Fi g, 4, keep all the settle7 of the stock, and the tendency of the staple is to wolk outwardly with relation to theinner sole rather than to be worked through "the'inner sole toward the boot, as with a common nail or screw driven into the inner sole l from the outer sole. A staple having its legs shaped as shown does not need to have its ends clinched or riveted. When a staple is einployed I am enabled to use, if desired, a thinner and cheaper' inner sole than can be practically used when nails and screws are inserted through the outer sole and upper and clinched or driven into the inner sole. The cross-bar e2 ot' each. ,staple will be embedded in the tread 'face of the inner sole, and will 'present a surface less objectionable to thc stocking and foot than the surface left by the points ot fastenings driven into it from the direction of the outer sole.

have considered it unthe exact construction S thc staples are shown In Figs. l, and S I necessary to represent ofthe staples. In Fig. in dotted lines.

b, will be ap-A sta-ples c e', a'nd then on the last It or subse- 3 of the bases of A machine for punching holes inthe upper will form the subject-matter of another application.

My vnovel process herein described might be practiced with good resultsv by sole-fastenings or staples of other shapes or. construction than that specifically shown at Fig. 4; but I do not herein claim a boot or shoe except when united andV held together bya staple substam' tiallysuchvas shown and described in Fig. 4.'

By the process described. boots and Vshoes maybe assembled and united .together very rapidly by means Ot' unskilled labor, and the boot or shoe herein described will be so securely held together that its soles cannot lseparate in wear or be pulled off or detached with any usual strain.

By employing the; thin supportfthe' upper may be liltedandmoved freely in any desireddirection when applying its perforated portions upon the legs of the staples set up in the inner sole. I have notched the uppcrtoleduce plaits at the toe.

By my process I avoid the usuatso-called lasting operation.

If a tap-sole should be desired, the staples e about the ball I am awa're that the soles of boots and, shoes have been held together outside the upper by staples,anti also that the soles and upper have vbeen-united by common staples driven through and toe of the boot or shoe in front ot the shank would-bc provided with' staples ot' a length sufficient to extend through .all the soles to be used..

'Instead ot' the round holes in. the upper, l might slot the uppenfrom the said holes to its edges tofacilitate the placing of the perforated parts of the upper over t-hev staples. 'I have shown two of the said y holes provided with slots, as at n.

It' the material of which the pper is coniposed is ot sutlicient strength, l may insert the legs of the staples through the holes in the inner sole from Vthe inner face of the upper, and then place the perforated'part'of the outer sole upon the legs of the said staplesas in the deein, Fig. 9.

I claim'- l. As an improved article of manufacturaa.

boot or shoe having an outer sole, inner solo', and upper united by staples having holdingprojections 3 thereon, such as described, and

inserted through the soles and upper with the cross-bar. of the staple next the inner sole, sul)- stanti-ally as described. .l

2. That improvement in the art or method of manufacturing boots and 'shoes which consists in rst'perfoiating the outer sole, inner sole, and upper for the reception of the solefastenings, inserting the sole fastenings through the holes in the inner sole from its upper or treadface, then placing the perfo'- rated portions of the upper and the outer sole over the projecting ends of the sole-fastenin gs, and forcing or pressing the soles and upper closely together, substantially as described.

3. The herein-described method of connecting the inner and outer soles and upper of tboot or shoe, which consists in punching holes in the said soles and upper for the reception of the metllic fasteningsr-nd subsequently inserting the metallic fastenin gs into the inner' sole, placing the latter, with itsinserted fast-y Jos.
